Description

Technical Field

[0001] This utility model relates to the technical field of marine display and control console equipment, specifically, it demonstrates a shielded heat dissipation display for a display and control console. Background Technology

[0002] Marine control consoles can monitor the status of shipboard equipment and issue fault alarms by receiving and transmitting status monitoring information and data. They also enable human-machine interaction and touch operation. Marine computer monitors are I / O devices for computers, used for control and operation on ships. They are display tools that transmit electronic documents through specific equipment to a screen and then reflect them to the human eye.

[0003] However, due to the presence of a strong low-frequency magnetic field in the ship, and the fact that the monitor is particularly sensitive to magnetic fields, this external magnetic field can cause serious changes in the displayed colors, resulting in distorted display patterns and poor anti-magnetic interference effects. Utility Model Content

[0004] The purpose of this invention is to provide a shielded heat dissipation display for a control console, which has a simple and practical structure and good heat dissipation and anti-magnetic interference effects.

[0005] The technical solution is as follows:

[0006] A shielded heat dissipation display for a control console includes a display module, a front frame, and a rear cover. The display module includes a cover glass, a touch film, a shielding film, and a liquid crystal display that are sequentially bonded together. The display module is bonded to the front frame, and a metal wire shielding braided mesh is provided between the display module and the front frame. The front frame and the rear cover are fixed by screws, and a conductive adhesive strip is provided between the front frame and the rear cover. A heat dissipation silicone pad is also provided between the lower part of the display module and the front frame.

[0007] Furthermore, the metal wire shielding mesh is embedded in the front frame and surrounds the entire perimeter of the liquid crystal display. This ensures a reliable fit between the cover glass and touch film and the front frame, and also solves the problem of incomplete tight contact between the shielding film and the front frame caused by processing flatness errors or cover glass adhesion errors, thus guaranteeing an effective shielding connection between the front end of the display module and the front frame.

[0008] Furthermore, the back of both the front frame and the back of the rear cover are provided with several evenly distributed heat dissipation grooves to increase the convection heat dissipation area and ensure effective heat dissipation of the LCD display.

[0009] Furthermore, the front frame has an audio / video driver board in the center of its back surface. The audio / video driver board is tightly fitted to the rear cover, and a silicone sheet is added between the audio / video driver board and the rear cover. This ensures that the heat-generating area of ​​the audio / video driver board is in close contact with the silicone sheet, effectively absorbing heat.

[0010] Furthermore, both the front frame and the rear cover are integrally molded. This ensures reliable structural strength, eliminates seams, and prevents electromagnetic leakage.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the whole machine shielding is formed by the tight connection of shielding film, metal wire shielding mesh, front frame, conductive rubber strip and back cover to form a complete shielding structure with electromagnetic conduction, ensuring reliable shielding performance requirements; the heat dissipation of the LCD display is mainly achieved through natural convection heat dissipation between the back of the front frame and the external environment.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] This utility model provides a shielded heat dissipation display for a display console, which solves the technical problems mentioned in the background art, so that the display has good anti-magnetic interference effect and heat dissipation effect.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown. Specifically, it mainly includes a display module 1, a front frame 2, and a rear cover 3. The display module 1 includes a cover glass, a touch film 11, a shielding film 12, and a liquid crystal display 13 that are sequentially bonded together. The display module 1 is bonded to the front frame 2, and a metal wire shielding braided mesh 4 is provided between the display module 1 and the front frame 2. The front frame 2 and the rear cover 3 are fixed by screws, and a conductive adhesive strip 5 is provided between the front frame 2 and the rear cover 3. A heat dissipation silicone pad 6 is also provided between the lower part of the display module 1 and the front frame 2.

[0020] By adding a shielding film 12 to the traditional fully laminated display module, the problem of not being able to set a conventional metal shielding structure at the front of the display is solved, ensuring effective shielding of the front of the display, while ensuring that the display effect is not affected and the touch is smooth.

[0021] A conductive adhesive strip 5 is added between the front frame 2 and the back cover 3 to further ensure an effective shielded connection between the front frame 2 and the back cover 3.

[0022] The heat dissipation of the LCD display 13 is mainly achieved through natural convection between the back of the front bezel and the external environment. The heat-generating components of the display are concentrated in the lower part of the display module. A boss structure can be designed at the corresponding position on the front bezel, and a heat-dissipating silicone pad can be added between the lower part of the display module and the boss on the front bezel to ensure that the heat-generating area of ​​the display module is in close contact with the front bezel housing.

[0023] The metal wire shielding mesh 4 is embedded in the front frame 2 and surrounds the LCD display 13. This ensures a reliable fit between the cover glass and the touch film and the front frame, and solves the problem of the shielding film not being able to make complete tight contact with the front frame due to processing flatness errors or cover glass pasting errors, thus ensuring an effective shielding connection between the front end of the display module and the front frame.

[0024] The overall heat dissipation design primarily addresses the cooling needs of the LCD monitor (thermal power consumption ≈ 35W) and the audio / video driver board (thermal power consumption ≈ 5W). Typically, the audio / video driver board 21 is located in the center of the back of the front bezel 2. The audio / video driver board 21 is tightly fitted to the rear cover 3, and a silicone pad 22 is added between the audio / video driver board 21 and the rear cover 3. This ensures that the heat-generating areas of the audio / video driver board are in close contact with the silicone pad, effectively absorbing heat.

[0025] The back of the front frame 2 and the back of the rear cover 3 are both provided with several evenly distributed heat dissipation grooves 7. This increases the convection heat dissipation area and ensures effective heat dissipation of the LCD monitor, thereby ensuring effective heat dissipation of the LCD monitor and audio / video driver board.

[0026] The front frame 2 and the rear cover 3 are both integrally molded. The structure is reliable in strength, with no splicing gaps, thus avoiding electromagnetic leakage.

[0027] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
